WebSep 3, 2024 · The degeneracy of Landau levels flanking charge neutrality in twisted bilayer graphene is known to change from eightfold to fourfold when the twist angle is reduced to values near the magic angle of ≈ 1. 05 ∘.This degeneracy lifting has been reproduced in experiments by multiple groups and is known to occur even in devices … WebOct 18, 2024 · We find that the degeneracy of Landau levels, which arises in the case of the constant magnetic field, lifts out when the field is variable and the energy levels of spin-up and spin-down electrons align in an interesting way depending on the nature of change of field. Also the varying magnetic field splits Landau levels of electrons with zero ... bradley s65-171
